This application is a Continuation of U.S. application Ser. No. 12/10,585, filed Apr. 10, 2008, which is a Continuation-in-Part of U.S. application Ser. No. 12/061,369, filed Apr. 2, 2008, which is a Continuation in Part of U.S. application Ser. No. 11/823,293, Jun. 27, 2007.

FIELD OF THE INVENTION

The present invention relates to household cleaning, fabric treatment, and deodorizing products that include an aqueous composition having hydrophilic, high molecular weight, perfume ingredients, packaged in a plastic container. The aqueous composition is in a solubilized or emulsified state and contains a substantial proportion of perfume ingredients with a Clog P less than about 3 and a boiling point greater than about 200° C., such that transmission of the perfume ingredients into and/or through the plastic container during storage is minimized and fragrance life, once dispensed from the container, is extended.

BACKGROUND

It is recognized that consumers appreciate household cleaning, fabric treatment and deodorizing products which impart a pleasant fragrance to surfaces treated with these products. For convenience and flexibility in use, it is highly desirable that household cleaning, fabric treatment, and deodorizing compositions be packaged in plastic containers as opposed to, for example, glass containers. For cost reasons, polyethylene is a preferred material for manufacturing plastic containers for such compositions. It has been found, however, that hydrophobic perfume ingredients have a tendency to be lost from the aqueous composition by absorption into and/or transmission through the polyethylene during storage of the composition. This results in a change in the perfume integrity or fragrance characteristics as well as a reduction in the fragrance life which would otherwise be obtained on surfaces treated with the composition. It has also been found that perfume ingredients with low boiling points, which have not been lost during storage, are more quickly lost than perfume ingredients with high boiling points once dispensed from the container.

SUMMARY OF THE INVENTION

The present invention relates to household cleaning, fabric treatment, or deodorizing products comprising an aqueous composition that includes from about 0.01% to about 50% of a surfactant and from about 0.003% to about 5% of a perfume, wherein the perfume contains at least about 10% of one or more hydrophilic perfume ingredients having a Clog P less than about 3 and a boiling point greater than about 200° C., and wherein the composition is contained in a plastic container constructed of at least about 80% hydrophilic perfume compatible materials. In one embodiment of the present invention, the aqueous composition is impregnated in a wet wipe or other substrate for cleaning or deodorizing surfaces.

The present invention also relates to a method of preserving perfume integrity and extending fragrance life in household cleaning, fabric treatment, or deodorizing products by providing an aqueous composition including from about 0.01% to about 50% of a surfactant and from about 0.003% to about 5% of a perfume, wherein the perfume contains at least about 10% of one or more hydrophilic perfume ingredients having a Clog P of less than about 3 and a boiling point greater than about 200° C., and packaging the composition in a plastic container constructed of at least about 80% hydrophilic perfume compatible materials.

BRIEF DESCRIPTION OF THE DRAWINGS

While the specification concludes with the claims particularly pointing and distinctly claiming the invention, it is believed that the present invention will be better understood from the following description taken in conjunction with the accompanying drawings in which:

FIG. 4 is a line graph illustrating the fragrance intensity over time of the same three perfumes illustrated in FIG. 3 but aged (subject to ambient temperatures or a 49° C. room for about two weeks or more).

DETAILED DESCRIPTION OF THE INVENTION

In accordance with the present invention it has been found that when household cleaning, fabric treatment, or deodorizing products comprising water, surfactant, and perfumes are packaged in conventional plastic containers, such as those constructed of high density polyethylene (HDPE), there is a tendency for certain perfume ingredients to be lost from the perfume. Without wishing to be bound by any particular theory, it is believed that perfume ingredients are lost by absorption of the hydrophobic perfume ingredients (i.e. those having a Clog P of about 3 or greater) into and/or transmission through the plastic container. When the perfume contains substantial amounts of such hydrophobic perfume ingredients, such loss considerably alters the integrity or intended fragrance of the perfume. Containers made of polyethylene terephthalate (PET) or glass do not exhibit a detrimental effect on hydrophobic perfume ingredients. However, consumers prefer plastic containers over glass for safety reasons with glass breaking, and plastic containers are generally less expensive than glass and PET. Material barriers to lessen the absorption and/or transmission of perfume ingredients into and/or through plastic containers have been considered but added production costs and time make this option undesirable.

It has now been found that the integrity of perfume ingredients can be better preserved in household cleaning, fabric treatment, and deodorizing products by utilizing a substantial amount of perfume ingredients that have a Clog P of less than about 3 and packaging the products in plastic containers constructed of at least 80% hydrophilic perfume compatible materials without the addition of material barriers in the plastic containers. The integrity of the perfume ingredients can be further enhanced by utilizing perfume ingredients with a Clog P of less than about 3 and a high boiling point; one that is greater than about 200° C.

The present invention is an household cleaning, fabric treatment or deodorizing product having an aqueous composition comprising, in addition to water, from about 0.01% to about 50% of a surfactant and from about 0.003% to about 5% of a perfume, wherein the perfume contains at least about 10% of one or more hydrophilic perfume ingredients having a Clog P of less than about 3 and a boiling point greater than about 200° C., and wherein the product is contained in a plastic container constructed of at least about 80% hydrophilic perfume compatible materials. In one aspect of the present invention, the aqueous composition is impregnated in a wet wipe or other substrate for cleaning or deodorizing surfaces.

The present invention also includes methods of preserving the integrity of perfume ingredients and extending fragrance life, by providing the aforesaid household cleaning, fabric treatment or deodorizing product.

A. Perfume

The aqueous compositions of the present invention contain perfumes at levels from about 0.003% to about 5%, alternatively from about 0.003% to about 1%, alternatively from about 0.01% to about 1%, alternatively from about 0.015% to about 0.5%, alternatively about 0.2% to about 0.4%, alternatively about 0.3% to about 0.4%, alternatively from about 0.05% to about 0.3%, alternatively from about 0.05% to about 0.2%, by weight of the composition. The perfumes selected for use in the compositions of the present invention contain ingredients with fragrance characteristics to provide a fresh impression on the surface to which the composition is directed.

Perfumes that are not too hydrophobic provide high initial fragrance impact on surfaces. The less hydrophobic perfume ingredients are more soluble in water, and are more available in the freshening composition. The degree of hydrophobicity of a perfume ingredient can be correlated with its octanol/water partitioning coefficient P. The octanol/water partitioning coefficient of a perfume ingredient is the ratio between its equilibrium concentration in octanol and in water. A perfume ingredient with a greater partitioning coefficient P is more hydrophobic. Conversely, a perfume ingredient with a smaller partitioning coefficient P is more hydrophilic. The perfume ingredients of this invention can have an octanol/water partitioning coefficient P of about 1,000 or smaller. Since the partitioning coefficients of the perfume ingredients normally have high values, they are more conveniently given in the form of their logarithm to the base 10, log P.

The log P of many perfume ingredients has been reported; for example, the Pomona 92 database, available from Daylight Chemical Information Systems, Inc. (Daylog CIS), Irvine, Calif., contains many, along with citations to the original literature. However, the log P values are most conveniently calculated by the “CLOG P” program, also available from Daylight CIS. This program also lists experimental log P values when they are available in the Pomona 92 database. The “calculated log P” (Clog P) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment approach is based on the chemical structure of each perfume ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. The Clog P values, which are the most reliable and widely used estimates for this physicochemical property, are used instead of the experimental log P values in the selection of perfume ingredients which are useful in the present invention.

In addition to providing the freshening fragrance to surfaces when first sprayed, the aqueous compositions of the present invention contain an effective amount of perfume to provide some lingering fragrance in wear, and some extra fragrance to be released upon rewetting. Fragrance life can be extended by utilizing perfume ingredients with a Clog P of less than about 3 and a boiling point greater than about 200° C. The evaporation rate of a perfume ingredient is inversely proportional to its boiling point; the higher the boiling point of a perfume ingredient, the lower the evaporation rate.

The aqueous compositions of the present invention contain a substantial portion of perfume ingredients (at least about 10%, alternatively at least 40%, alternatively at least 70%) which have a Clog P of less than 3 and a boiling point greater than about 200° C. At least about 10%, alternatively at least about 40%, alternatively at least about 70% by weight of the perfume is composed of perfume ingredients which include aromatic and aliphatic esters having molecular weights from about 130 to about 250; aliphatic and aromatic alcohols having molecular weights from about 90 to about 240; aliphatic ketones having molecular weights from about 150 to about 260; aromatic ketones having molecular weights from about 150 to about 270; aromatic and aliphatic lactones having molecular weights from about 130 to about 290; aliphatic aldehydes having molecular weights from about 140 to about 200; aromatic aldehydes having molecular weights from about 90 to about 230; aliphatic and aromatic ethers having molecular weights from about 150 to about 270; and condensation products of aldehydes and amines having molecular weights from about 180 to about 320. The perfume ingredients can be essentially free from nitromusks and halogenated fragrances. Non-limiting examples of suitable perfume ingredients include those listed in Table 1 and mixtures thereof.

Highly water-soluble cyclodextrins are those having water solubility of at least about 10 g in 100 ml of water at room temperature, alternatively at least about 20 g in 100 ml of water, alternatively at least about 25 g in 100 ml of water at room temperature. The availability of solubilized, uncomplexed cyclodextrins is essential for effective and efficient odor control performance. Solubilized, water-soluble cyclodextrin can exhibit more efficient odor control performance than non-water-soluble cyclodextrin when deposited onto surfaces, especially fabric.

Examples of water-soluble cyclodextrin derivatives suitable for use herein are hydroxypropyl alpha-cyclodextrin, methylated alpha-cyclodextrin, methylated beta-cyclodextrin, hydroxyethyl beta-cyclodextrin, and hydroxypropyl beta-cyclodextrin. Hydroxyalkyl cyclodextrin derivatives can have a degree of substitution of from about 1 to about 14, alternatively from about 1.5 to about 7, wherein the total number of OR groups per cyclodextrin is defined as the degree of substitution. Methylated cyclodextrin derivatives typically have a degree of substitution of from about 1 to about 18, alternatively from about 3 to about 16. A known methylated beta-cyclodextrin is heptakis-2,6-di-O-methyl-β-cyclodextrin, commonly known as DIMEB, in which each glucose unit has about 2 methyl groups with a degree of substitution of about 14. A more commercially available methylated beta-cyclodextrin is a randomly methylated beta-cyclodextrin, commonly known as RAMEB, having different degrees of substitution, normally of about 12.6. DIMEB affects the surface activity of the surfactants more than RAMEB. Cyclodextrins are available from Cerestar USA, Inc. and Wacker Chemicals (USA), Inc.

A mixture of cyclodextrins can be used in the present invention. The amount of cyclodextrins used in the compositions can range from about 0.01% to about 20% by weight of the aqueous composition. If the composition is intended to be diluted before use it will contain from about 3% to about 20%, alternatively about 5% to about 10%. Compositions intended to be used in undiluted form will generally contain from about 0.01% to about 5%, alternatively about 0.1% to about 3%, alternatively about 0.5% to about 2%.

When formulating compositions with cyclodextrins, surfactants which have especially good compatibility with cyclodextrin can be used. Suitable cyclodextrin-compatible surfactants can be readily identified by the absence of effect of cyclodextrin on the surface tension provided by the surfactant. This is achieved by determining the surface tension (in dyne/cm²) of aqueous solutions of the surfactant in the presence and in the absence of 1% of a specific cyclodextrin in the solutions. The aqueous solutions contain surfactant at concentrations of approximately 0.5%, 0.1%, 0.01%, and 0.005%. The cyclodextrin can affect the surface activity of a surfactant by elevating the surface tension of the surfactant solution. If the surface tension at a given concentration in water differs by more than about 10% from the surface tension of the same surfactant in the 1% solution of the cyclodextrin, that is an indication of a strong interaction between the surfactant and the cyclodextrin. The surfactants herein can have a surface tension in an aqueous solution that is different (lower) by less than about 10%, alternatively less than about 5%, and alternatively less than about 1% from that of the same concentration solution containing 1% cyclodextrin.

(a) Block Copolymers

Non-limiting examples of cyclodextrin-compatible nonionic surfactants include block copolymers of ethylene oxide and propylene oxide. Suitable block polyoxyethylene-polyoxypropylene polymeric surfactants, that are compatible with most cyclodextrins, include those based on ethylene glycol, propylene glycol, glycerol, trimethylolpropane and ethylenediamine as the initial reactive hydrogen compound. Polymeric compounds made from a sequential ethoxylation and propoxylation of initial compounds with a single reactive hydrogen atom, such as C₁₂₋₁₈ aliphatic alcohols, are not generally compatible with the cyclodextrin. Certain of the block polymer surfactant compounds designated Pluronic® and Tetronic® by the BASF-Wyandotte Corp., Wyandotte, Mich., are readily available.

Non-limiting examples of cyclodextrin-compatible surfactants of this type include: Pluronic Surfactants with the general formula H(EO)_(n)(PO)_(m)(EO)_(n)H, wherein EO is an ethylene oxide group, PO is a propylene oxide group, and n and m are numbers that indicate the average number of the groups in the surfactants. Typical examples of cyclodextrin-compatible pluronic surfactants are:

Name Average MW Average n Average m L-101 3,800 4 59 L-81 2,750 3 42 L-44 2,200 10 23 L-43 1,850 6 22 F-38 4,700 43 16 P-84 4,200 19  43,

and mixtures thereof.

Tetronic Surfactants with the General Formula:

wherein EO, PO, n, and m have the same meanings as above. Typical examples of cyclodextrin-compatible tetronic surfactants are:

Name Average MW Average n Average m 901 4,700 3 18 908 25,000 114  22,

and mixtures thereof.

“Reverse” Pluronic and Tetronic surfactants have the following general formulas:

Reverse Pluronic Surfactants H(PO)_(m)(EO)_(n)(PO)_(m)H Reverse Tetronic Surfactants

wherein EO, PO, n, and m have the same meanings as above. Typical examples of cyclodextrin-compatible reverse pluronic and reverse tetronic surfactants are:

and mixtures thereof.

(b) Siloxane Surfactants

Another class of cyclodextrin-compatible nonionic surfactants are the polyalkyleneoxide polysiloxanes having a dimethyl polysiloxane hydrophobic moiety and one or more hydrophilic polyalkylene side chains and have the general formula:

R¹—(CH₃)₂SiO—[(CH₃)₂SiO]_(a)—[(CH₃)(R¹)SiO]_(b)—Si(CH₃)₂—R¹

wherein a+b are from about 1 to about 50, alternatively from about 3 to about 30, alternatively from about 10 to about 25, and each R¹ is the same or different and is selected from the group consisting of methyl and a poly(ethyleneoxide/propyleneoxide) copolymer group having the general formula:

—(CH₂)_(n)O(C₂H₄O)_(c)(C₃H₆O)_(d)R²

with at least one R¹ being a poly(ethyleneoxide/propyleneoxide) copolymer group, and wherein n is 3 or 4, alternatively 3; total c (for all polyalkyleneoxy side groups) has a value of from about 1 to about 100, alternatively from about 6 to about 100; total d is from 0 to about 14, alternatively from 0 to about 3; and alternatively d is 0; total c+d has a value of from about 5 to about 150, alternatively from about 9 to about 100 and each R² is the same or different and is selected from the group consisting of hydrogen, an alkyl having 1 to 4 carbon atoms, and an acetyl group, alternatively hydrogen and methyl group.

Examples of this type of surfactant are the Silwet® Hydrostable 68, 611, and 212 available from Momentive Performance Materials. Other representative Silwet surfactants are as follows.

Name Average MW Average a + b Average total c L-7608 600 1 9 L-7607 1,000 2 17 L-77 600 1 9 L-7605 6,000 20 99 L-7604 4,000 21 53 L-7600 4,000 11 68 L-7657 5,000 20 76 L-7602 3,000 20 29

The molecular weight of the polyalkyleneoxy group (R¹) is less than or equal to about 10,000. Alternatively, the molecular weight of the polyalkyleneoxy group is less than or equal to about 8,000, and alternatively ranges from about 300 to about 5,000. Thus, the values of c and d can be those numbers which provide molecular weights within these ranges. However, the number of ethyleneoxy units (—C₂H₄O) in the polyether chain (R¹) must be sufficient to render the polyalkyleneoxide polysiloxane water dispersible or water soluble. If propyleneoxy groups are present in the polyalkylenoxy chain, they can be distributed randomly in the chain or exist as blocks. Besides surface activity, polyalkyleneoxide polysiloxane surfactants can also provide other benefits, such as antistatic benefits, lubricity and softness to fabrics.

The preparation of polyalkyleneoxide polysiloxanes is well known in the art. Polyalkyleneoxide polysiloxanes of the present invention can be prepared according to the procedure set forth in U.S. Pat. No. 3,299,112, incorporated herein by reference. Typically, polyalkyleneoxide polysiloxanes of the surfactant blend of the present invention are readily prepared by an addition reaction between a hydrosiloxane (i.e., a siloxane containing silicon-bonded hydrogen) and an alkenyl ether (e.g., a vinyl, allyl, or methallyl ether) of an alkoxy or hydroxy end-blocked polyalkylene oxide). The reaction conditions employed in addition reactions of this type are well known in the art and in general involve heating the reactants (e.g., at a temperature of from about 85° C. to 110° C.) in the presence of a platinum catalyst (e.g., chloroplatinic acid) and a solvent (e.g., toluene).

(c) Anionic Surfactants

Non-limiting examples of cyclodextrin-compatible anionic surfactants are the alkyldiphenyl oxide disulfonate, having the general formula:

wherein R is an alkyl group. Examples of this type of surfactants are available from the Dow Chemical Company under the trade name Dowfax® wherein R is a linear or branched C₆-C₁₆ alkyl group. An example of these cyclodextrin-compatible anionic surfactant is Dowfax 3B2 with R being approximately a linear C₁₀ group. These anionic surfactants are alternatively not used when the antimicrobial active or preservative, etc., is cationic to minimize the interaction with the cationic actives, since the effect of both surfactant and active are diminished.

The surfactants above are either weakly interactive with cyclodextrin (less than 5% elevation in surface tension, or non-interactive (less than 1% elevation in surface tension). Normal surfactants like sodium dodecyl sulfate and dodecanolpoly(6)ethoxylate are strongly interactive, with more than a 10% elevation in surface tension in the presence of a typical cyclodextrin like hydroxypropyl beta-cyclodextrin and methylated beta-cyclodextrin.

Typical levels of cyclodextrin-compatible surfactants in aqueous compositions of the present invention are from about 0.01% to about 2%, alternatively from about 0.03% to about 0.6%, alternatively from about 0.05% to about 0.3%, by weight of the composition. Typical levels of cyclodextrin-compatible surfactants in concentrated compositions are from about 0.1% to about 8%, alternatively from about 0.2% to about 4%, alternatively from about 0.3% to about 3%, by weight of the concentrated composition.

Deodorizing compositions containing cyclodextrin are more fully described in U.S. Pat. No. 6,767,507.

D. Wipes

The aqueous compositions of the present invention may be impregnated into a commercially available substrate such as the substrates discussed in U.S. Pat. No. RE 38505, U.S. Pat. No. RE 38105, and U.S. Pat. No. 6,936,330, all of which are incorporated herein by reference. In one embodiment, the substrate may be a non-woven, wet-wipe for deodorizing, disinfecting, or cleaning multiple surfaces including inanimate household surfaces.

E. Packaging Container

The aqueous compositions of the present invention can be contained in plastic containers constructed of hydrophilic perfume compatible materials. These materials avoid complexing with hydrophilic perfume ingredients, such that absorption by and/or transmission through plastic containers is minimized. Suitable hydrophilic perfume compatible materials can be readily identified by determining the average hydrophilic perfume loss through gas chromatography analysis. Hydrophilic perfume compatible materials result in an average hydrophilic perfume ingredient loss of less than about 50%, alternatively less than about 20%, alternatively less than about 15% and alternatively less than about 10% of the originally present individual hydrophilic perfume ingredients.

Aqueous compositions containing a substantial amount of hydrophilic perfume ingredients can be stored in plastic container constructed of at least 80% hydrophilic perfume compatible materials for 8 weeks at ambient temperature. After storage, gas chromatography analysis is used to determine the amount of the various perfume ingredients remaining in the aqueous composition and approximate loss is calculated, based on the amount of each ingredient originally present.

An effective amount of hydrophilic perfume compatible materials suitable for the present invention is at least about 80%, alternatively about 80% to about 100%, alternatively about 90% to about 100%, and alternatively 100%, by weight of the container. Non-limiting examples of hydrophilic perfume compatible materials are any resins of high density polyethylene (HDPE), low density polyethylene (LDPE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), polyethylene-co-vinyl alcohol (EVOH), fluorinated polymer such as Aclar®, acrylonitrile-methyl acrylate copolymer such as Barex®, or mixtures thereof. Alternatively, HDPE is utilized in the present invention.

In one embodiment, an HDPE bottle, from Plastipak Packaging Inc, Champaign, Ill., is used to contain the aqueous composition of the present invention. HDPE bottles can be made by any blow molding, injection molding, and thermoform process known in the art. For example, for blow molded bottles, heat softened HDPE is extruded as a hollow tube into a mold cavity and forced by pressurized air against the walls of the cold mold cavity to form the bottle. The bottle solidifies by cooling.

It has been found that the perfume compositions having a Clog P of less than about 3 are not fully absorbed into and/or transmitted through the hydrophilic perfume compatible materials such as PP and HDPE. Thus, this assists in preventing transmission of perfume ingredients through plastic containers; which in turn provides consumer noticeable, longer lasting fragrance life.

Any of the hydrophilic perfume compatible materials can be used in conjunction with one or more barrier materials including amorphous carbon, silicone oxide or mixtures thereof, and metallized coating. The following examples are presented for illustrative purposes, and are not intended, in any way, to limit the scope of the invention.

Example I

In this example, two deodorizing compositions for inanimate surfaces (e.g. rugs, clothing, counter tops, etc.) are evaluated in 800 ml plastic bottles, constructed of 52 g of HDPE (100% by weight of the bottle), for preserving perfume integrity or minimizing loss of fragrance. The first composition, Composition A, is approximately 0.05% perfume, made up of at least about 47.9% perfume ingredients having a Clog P less than about 3 and a boiling point greater than about 280° C. The second composition, Composition B, is approximately 0.05% perfume, made up of 40.8% perfume ingredients having a Clog P greater than about 3 and a boiling point greater than about 280° C. The control perfume is approximately 0.05% perfume of which 18.7% are perfume ingredients having a Clog P of less than 3 and a boiling point greater than about 280° C.

Panelists evaluate the freshly made and aged compositions (A, B, and Control) for their respective fragrance intensities after the following intervals: immediately after the compositions are sprayed onto fabric, at 2 hours, at 24 hours, and at 48 hours. The freshly made compositions are those that are evaluated immediately after being made or within about two weeks of being properly stored in a 4° C. constant temperature, constant humidity (CTCH) room. The aged compositions are those that have been subject to ambient temperatures or a 49° C. room for about two weeks or more.

FIG. 1 and Table 5 show the fragrance intensity of the fresh compositions over time. At 48 hours, Composition A shows a grade of 40, Composition B shows a grade of 35, and the Control composition shows a grade of 20 at 48 hours.

FIG. 2 and Table 6 show the fragrance intensity of the aged compositions on fabric over time. At 48 hours, Composition A shows a grade of 25, Composition B shows a grade of 20 and the Control Composition shows a grade of 10. The difference between consumer noticeable fragrance and fragrance that is not consumer noticeable is a grade of at least 15. In the aged products, the control is not consumer noticeable but Compositions A and B are consumer noticeable.

Overall, perfume intensity of Composition A and Composition B are retained after 48 hours from when the perfumes are sprayed onto fabric. At 48 hours, perfume character comments included “distinct citrus” for Composition A and “distinct citrus freshness” for Composition B.

Example II

In this example, two more deodorizing compositions for inanimate surfaces (e.g. rugs, clothing, counter tops, etc.) are evaluated in 800 ml plastic bottles, constructed of 52 g of HDPE (100% by weight of the bottle), for preserving perfume integrity or minimizing loss of fragrance. The first composition, Composition C, is approximately 0.065% perfume, made up of at least about 47.9% perfume ingredients having a Clog P less than about 3 and a boiling point greater than about 280° C. The second composition, Composition D, is approximately 0.065% perfume, made up of about 34.4% perfume ingredients having a Clog P less than about 3 and a boiling point greater than about 280° C. The control perfume is approximately 0.05% perfume of which 18.7% are perfume ingredients having a Clog P of less than 3 and a boiling point greater than about 280° C. Panelists evaluate the fresh and aged perfumes according to the steps identified in Example I. FIG. 3 and Table 7 show the intensity of the fresh compositions on fabric over time.

Example III

An aqueous composition suitable for use in the invention is formulated as follows.

Components: Wt. % DI Water 94.968 Ethanol 3.000 Diethylene Glycol 0.250 Surfactant 0.100 Uniquat 2250 0.060 Basophor ELH60 0.050 Triethanolamine 0.300 Perfume 0.250 Hydroxypropyl Beta Cyclodextrin 0.900 Koralone B-119 0.015 Citric Acid 0.100 5% NaOH 0.007 100.000

The aqueous composition is stored in HDPE containers for about 8 weeks at ambient temperature. After storage, gas chromatography analysis is used to determine the amount of the perfume ingredients in Table 9 which are remaining in the composition. Approximate loss is calculated based on the amount of each ingredient originally present.

TABLE 9 Perfume Ingredients Perfume Ingredients with Clog P < 3 with Clog P > 3 Oxane Allyl Caproate Carvone Neral Methyl phenyl carbinyl acetate Geranial Methyl dihydro jasmonate Citronellyl nitrile Ligustral Dihydro myrcenol Diethyl phthalate Geraniol Cumin aldehyde Citronellal Tetrahydro linalool 3-Decanone Floralozone Flor acetate Bourgeonal beta-ionone gamma-damascone alpha-damascone Verdox Vertenex Decanal Sabinene Undecavertol Frutene Gamma-trepinene beta-pinene 2-Methyl heptenone alpha-pinene delta-3-carene alpha-terpinene Allo ocimene Ethyl decanoate Tangerinol Isopropyl myristate

The average percent loss is less than 50% for perfume ingredients with a Clog P less than 3 and greater than 70% for perfume ingredients with a Clog P greater than 3. This example demonstrates that perfume ingredients with a Clog P greater than 3 undergo significant loss when stored in HDPE containers.
